HYDRAULIC SAUSAGE-STUFFING,MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,323, dated March26, 1889.

Application filed December 20, 1888. Serial No. 294.139. (N model.)

To (LZZ whont it ntag concern: Be it known that I, HENRY GEYER, ofBrooklyn, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Apparatus for Stuffing Sausagesand for Pressing Various Materials; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings and to the letters of reference markedthereon, making a part of this specification.

My invention relates to machines for stuffing sausages or pressing lardor fruits, 850.,

and has for its object to provide a simple apparatus for the purpose,which may be worked by water-pressure with rapidity and economy.

It consists in the combination in a compact form of an improvedhydraulic engine with a forcing or pressing cylinder, the whole beingconstructed and arranged substantially as is hereinafter describedandclaimed.

In the accompanying drawings, Figure 1 is an elevation of my improvedapparatus with the forcing or pressing cylinder partlyin section; Fig.2, a central vertical section in line 00 0c of Fig. 1; Fig. 3, atransverse section in line y 3 of Fig. 1, and Fig. l a sectional detailof the supply-valve on an enlarged scale in line 2' of Fig. 2.

Similar letters indicate like parts in all of the figures.

A represents the open-top forcing or press ing cylinder having a base,B, adapted to slide into a dovetailed seat or recess in the bed-plate Cof the apparatus. This open cylinderA is fitted with a stuffing-nozzle,A, governed in the usual manner by a gate or valve, A and is adapted toreceive a piston, D, provided with a peripheral packing-ring, E, ashereinafter described,whereby a close joint is made between the pistonand the inner periphery of the cylinder under pressure.

F is a hydraulic cylinder mounted centrally over the pressing-cylinder,so that the axis of the two shall coincide. It is supported in positionbetween two transverse plates, G G, which are mounted parallel with thebase B upon vertical rods or standards G G G2 G the rods G G being madeto pass through apertures in the projecting rim of the lower head-plate,F, of the cylinder to confine the same, and fitted with nuts by whichthe plates cient space is allowed between the top of thepressing-cylinder A and the superimposed cross-plate G, supporting thehydraulic cylinder, to allow the piston D of the pressing-cylinder to belifted up entirely clear of said cylinder, so as to permit of a readyremoval of the latter for refilling and replacement. Saidpressing-piston D is constructed of a disk, a, made fast to thepiston-rod, and a second corresponding disk, Z), fitted to play looselyto and from the first upon a central axial pin, 0, forming an extensionof the piston-rod, the disk being prevented from slipping off of the pinby a terminal nut, (Z. The outer rim of each plate is inwardly beveled,so that a seat is thereby formed between the two, in which is fitted aring, E, of rubber or other elastic material. "Vhen the disk 6 is freefrom pressure, so as to hang loosely, as is the case when the pistonmoves upward, the ring E will automatically contract within its seat andnot project peripherally beyond the edge of the disks, so that thepiston will move upward freely without friction against the sides of thecylinder; but when the piston, moving downward, is brought into contactwith the contents of the cylinder and made to bear thereon the pressureof the loose disk 1) upon the ring E, as the disk is forced upward inbearing upon said contents, will, by compressing the ring, cause it toexpand and closely pack the joint between the piston and cylinder.

The piston H in the workirig-cylinder F is driven alternately inopposite directions by means of the pressure of a column of wateradmitted alternately to the opposite sides thereof through suitableinlet-pipes, K K, by the operation of a rotating valve, Y, in a suitablevalve-chamber, L, connected with a water-supply pipe, L. This valve isconstructed of a rotating disk, 1%, having two ports therein at equaldistances from its center and separated by an arc of about ninetydegrees. The disk is mounted on a central spindle within thevalve-chamber, (see Fig. 2,) to revolve over the face of a valve-seat,01, having corresponding ports formed therein at the same radialdistance from the center as the ports in the su lerimposed disk m, butwhich are formed at (liailietrically-opposite points, Fig. i,) so that ahalf-turn of the disk in either direction will close one of the ports inthe seat a and open the other, by reason of the registry therewith ofthe one port or the other in the disk m. The disk n) is held closelyupon its seat to form a water-tight joint by means of a coiled spring,0, encircling its spindle. The valve-spindle is made to project outthrough a stuffing-box in the cover of the valve-chamber L, and isfitted at its outer end with an arm or lever, M, by which it isactuated, and with a second weighted eouiiterbalancingarm, N, extendingradially therefrom at an angle of ninety degrees with the actuatingarmM. The two arms are so ax'ljusted with regard to the valve as that theweight of the arm M shall operate automatically to open one or other ofthe valve-ports.

Valor is admitted under pressure to the valvechamber L through the suiply-pipe ll, which is overned by a controlling-valve, V, and :iiowsfree through the open port of the valve into the etn'responding end ofthe working-cylinder l so as to force the piston ll therein to theopposite end.

The exhaust ot' the tluid in frontof the piston is provided for by meansof a dischargepipe, lrt, fitted to each inletpipe K to form a counectiimthrough it with the inlet-port Q of the cylinder, so that the exhaustmay take place through said port. A valve, T, is seated in thedischarge-pipe beyond said port to be closed by the pressure of waterthereon in the inlet-pipe. The valve automaticallydrawn back from itsseat to open the disclmrge- 'iipe, when it is released from the pressureof a water eolumnin the inlet-pipe, by means of a spring, B, so that thedischarge-port remains normally open whenever the water-supply is cutoil? by the valve Y from said inlet-pipe. The valve Y is turnedautomatically, so as to open the one port and close the other as theconnected pistons approach the end oi. their stroke in either directionby means of a rod, T, made fast to the piston-rodl, to move paralleltherewith outside of the hydraulic pistoneylinder, as shown in Fig. 1.,and which is fitted with trip pin g collars or tappets \V \V, adjustable thereon, and adapted to engage the end of the lever-arm M ofthe valve, the arm being so propmtioned in length and bent as tofacilitate said engagement. As the pistons approach the end of theirstroke, one of said colla rs will bear upon the end of the lever-arm Mand move it until the weighted arm N is brtmght to a vertical positionand the open port of the valve thereby closed, while the slight furthermovement of the pistons due to their momentum will carry the weight-edarm over the center, so that it will drop antomatically on the oppositeside, and in so dropping will open wide the other supply-port and admitthe water to the opposite end of the piston. he soon as the water isthus admitted under pressure into either illtlllCliltDllpipe K itwillovercomethe stress of the spr ng S, g .verning the valve l, atthecorrespond ing induction-port ot' the cylinder and lorce sald valveagainst its seat in the discharge-pipe to close it and simultaneouslyopen a free passage for the intiowing water from the pipe K into thecylinder through the port Q. (onversely, so soon the pressure in theopposite ind Ll(fl)l0]l-])l])0 is cut oil the spring S, governing thevalve 1 in that pipe, will cause the valve to lift from the exhaust-portand thereby open a tree passage from the discharge ol' water from thatend of the cylinder through the port Q. The apparatus is thus automaticin its action, and the pistons will alternately rise and [all with apower due to the pressure of the water upon the piston ll, its movementbeing arrested at will at anypoint in its stroke by cutting oli thewater-supply by means ot the controlling-valve 'V.

The upper end of the actuating-rod 'l is supported and its vibrationprevented by means of an embracing-fork, '1, upon the end of aboutlever, 11, pivoted to the side of the cylinder, so that one arm thereofshall extend out horizontally to earrytheifork into engagement with therod, while its second arm projects downward and rests against a coiledspring, 10. The horizontal. arm :is thus left free to yield downwardsui'liciently to allow the tappet \V to pass it as it moves downward,and is also free to swing upward and clear the tappet as it movesupward, after which it will drop again, by reason oi its weight, toembrace the rod below the collar.

\Yhen the piston l) is lilfted out ot the prcssirig-cylinder A,thecylinder can be readily removed and replaced. The downward descent ofthe piston I), under the pressure of the water upon the piston ll, willcause the meat in the pressing-cylinder to be expelled with a steadyuniform movement through the stu fling-nozzle A.

This apparatus is adapted for use in connection with the water-servicein towns and cities, it being only necessary to connect the supply-pipeL with a supply-fzuwet and the exhaust-pipes R R with a sink by meansol; detachable rubber hose in order to obtain the necessary power to runit.

I claim. as my invention- 1. The combination of the hydraulic cylinder,the piston working therein, the inletpipes communicating with either endof said cylinder, the rotating two-way valve controlling said pipes, thecounterbalanced lever actuating said valve, and the spring-aetuatedvalves governing the exhzuist-port at each end of the cylinder, saidvalves being titted within the inlet-pipes, each to be closed by thepressure of water admitted thereto and be automatically opened by itsspring when the pressure ceases, substantially in the manner and for thepurpose herein set forth.

2. The combination of the hydraulic cylin der, the piston workingtherein, the inlet- ITO pipes communicating with either end of saidcylinder, the rotating two-way valve controlling said pipes, thecounterbalanced lever actuatin g said valve, the spring-actuated valvesgoverning the exhaust-port at each end of the cylinder and fitted withinthe inlet-pipes, each to be closed by the pressure of water admittedthereto and be automatically opened by its spring when the pressureceases, the pressing-cylinder mounted beneath the hydraulic cylinder,the piston therein connected with the piston of said hydraulic cylinder,the valve-actuating rod moving in unison with the piston, the leverprojecting from the spindle of the rotating inlet-valve for thehydraulic cylinder, the tappets fitted on the valve-actuating rod toengage said lever, and the counterbalancing-lever projecting radiallyfrom said valve-spindle, whereby when said lever is carried by themovement of the actuating-rod to and by its center of gravity above thevalve to close one inlet-port it will automatically drop to open theother port and thereby reverse the movement of the piston, substantiallyin the manner and for the purpose herein set forth.

3. The combination, with the inlet pipe and port of the hydraulicpiston-cylinder, as described, of a discharge-pipe connected directlywith said inlet-pipe beyond said port, a valve closing saiddischarge-pipe and subjected to the pressure Within the inlet-pipe, anda spring actuating the valve to open it automatically when it isrelieved from said pressure, substantially in the manner and for thepurpose herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
